Roma will be keen to build on their midweek Coppa Italia success by beating Fiorentina, at the Stadio Artemio Franchi.

The teams had differing fortunes in the opening legs of the semi-finals this week, with Roma easing past Udinese 2-0 while the Viola lost out to Inter Milan by the narrowest of margins.

However, both clubs now face a long wait to see whether they will meet in the final, with the return matches not scheduled until mid-April.

Roma boss Claudio Ranieri admits the timing of the fixtures is far from ideal for all four clubs involved.

"Whoever decided the dates of the Coppa Italia is clearly a genius," he said. "It's like playing the first half and returning two months after the interval.

"If we could finish the fixture in a week, as planned, it would be a completely different story.

"They're trying to give credibility to this tournament but then something like this is decided.

"In two months we should be fine and we should be playing even better. But then again, two months from now who knows what could happen?"

In the meantime, Roma's attention will switch back to Serie A with the possibility of taking second spot from AC Milan this weekend if results go their way.

The Bianconeri will be boosted by the return of captain Francesco Totti, who has recovered from a knee injury which has kept him sidelined since the winter break.

Totti came back into the side for the cup clash with Udinese and suffered no reaction to the fitness problems which have troubled him in recent weeks.

On loan striker Luca Toni remains sidelined with a calf injury though, while Nicolas Burdisso is suspended for the trip to Florence.

Fiorentina have more than just Coppa Italia concerns at present with the Viola sliding down to 11th in the league after taking one point from their last three matches.

With a seven-point gap to make up on the top four, coach Cesare Prandelli needs to find some inspiration to get his team back on track.

The arrival of Brazilian striker Keirrison on loan from Barcelona this week could be the spark they need, and he is hoping to make his bow against Roma tomorrow.

"I am very happy to have arrived at a big club like Fiorentina," said Keirrison. "I am ready to play.

"I am proud to have arrived in Italy and I hope to do well and score many goals for this team."

Prandelli remains without striker Adrian Mutu, who has been suspended indefinitely after testing positive for the banned substance sibutramine.

Felipe is also serving a one-match ban for the Viola while Per Kroldrup and Cristian Zanetti are injured.
